可以看到，版本是5.0.5，数据目录是/data，端口是6379。

下面创建容器

[root@localhost admin]# docker run --name some-redis -p 6379:6379 -d --privileged -v /usr/local/redis_data:/data redis redis-server --appendonly yes

创建并启动成功。

参数解释：

docker run --name some-redis -p 6379:6379 -d --privileged -v /usr/local/redis_data:/data redis redis-server --appendonly yes

--name：容器命名
-p：宿主机端口:容器内端口
-d：后台启动
--privileged：【chown: changing ownership of '.': Permission denied】授权
-v：将容器内的目录挂载到宿主机目录
redis：镜像名称
redis-server --appendonly yes：容器内执行redis-server命令，并打开持久化

　　

在本地用redis客户端连接容器redis：

redis-cli.exe -h 192.168.192.128 -p 6379

 简单测一下：

然后回到容器，看一下有没有
